The Samsung Galaxy Book 2 Pro, Samsung's laptop with Intel's discrete Arc Alchemist graphics engine, was briefly sold by B&H Photo Video. According to the listing, Samsung is one of the manufacturers to use Intel's independent GPU. 

When top-of-the-line Samsung laptops are compared year after year, it appears that Samsung is only charging a $50 premium for the discrete GPU. The main feature we noted from the now-removed ad at B&H PhotoVideo (via VideoCardz) for $1,349.99 is a standalone Arc graphics processor from Intel based on the Xe-HPG architecture and belonging to the DG2 series. The listing emphasizes that the Arc GPU it employs is meant to provide improved performance in both content development tasks and gaming. Intel's Iris Xe Max, on the other hand (an Intel DG1 GPU based on the Xe-LP architecture) was designed primarily to offload content production duties off integrated graphics.
